Live repository

Not pinned. Installing fetches whatever the repository holds at the time you run the command.

No human has reviewed this code. The checks below are a static scan of the files at one commit — nobody has run this skill or judged whether it works. A skill runs with whatever access you give your agent, so read the source before you install it.

Automated safety checks

scanned

This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.

  • Declares what it does: passed

    SKILL.md parses and declares a name and a description.

    SKILL.md exists, its frontmatter parses, and it declares a name and a description.

  • No undeclared network calls: passed

    Makes no network calls.

    Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.

  • No obfuscated payloads: passed

    No encoded or obfuscated payloads.

    No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.

  • No credential access: passed

    Reads no keys, tokens, keychains or credential files.

    Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.

  • No pipe-to-shell installers: passed

    No pipe-to-shell or download-and-run installers.

    No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

  • Pinned to a commit: passed

    Scanned farming-labs/fm-skills at a432a4fbfd.

    The exact upstream commit SHA that was scanned is recorded, so the result refers to specific bytes.

This is a static scan, not a review. It reads the skill's files; it does not run them, and it cannot tell you whether the skill is any good or whether the code does what its description says. A skill runs with whatever access you give your agent.

About this skill

What it does

This skill provides a JavaScript runtime environment, enabling AI agents to execute JavaScript code directly. It allows for tasks like processing data with JavaScript libraries, interacting with APIs that require JavaScript payloads, and performing complex calculations or transformations within the agent's workflow. The runtime supports standard JavaScript features and common Node.js modules.

When to use it

  • Data Transformation: When you need to manipulate data using JavaScript-specific libraries (e.g., Lodash, Moment.js) that aren’t readily available in other languages within the agent environment.
  • API Interaction: To construct and send complex JavaScript objects as payloads when interacting with APIs that expect them.
  • Complex Calculations: For performing intricate mathematical operations or simulations best suited to a JavaScript runtime.
  • Code Execution: When you need to execute arbitrary Javascript code snippets within the agent's context.

Key capabilities

  • JavaScript execution environment
  • Support for Node.js modules
  • Standard JavaScript features compatibility
  • Data processing with JavaScript libraries

Example prompts

  • "Calculate the Fibonacci sequence up to the 10th term using Javascript."
  • "Format this date string '2023-10-27' into a more readable format using Moment.js in Javascript."
  • “Send this JSON payload to the API endpoint: { "key": "value" }”

Tips & gotchas

The agent needs access to necessary Node.js modules for specific tasks; ensure these are available within the runtime environment. Be mindful of potential security implications when executing arbitrary JavaScript code, as it can impact the agent's overall safety and reliability.
